Background:    It is unclear whether alcohol detoxification has an effect on factors that are involved in growth, metabolic functions and cell proliferation. Alcohol abuse is associated with low IGF-I levels that tend to rise after alcohol withdrawal. There is a paucity of studies on the course of IGFBP-3 (the main binding protein for IGF-I) after alcohol detoxification.
    Material/Methods:    We prospectively assessed IGF-I and IGFBP-3 changes at the time of admission and after 4 to 6 weeks of detoxification in an inpatient alcohol detoxification facility in 118 alcohol-dependent subjects given a regular hospital diet. No participants dropped out of the study.
    Results:    Changes in IGF-I after alcohol detoxification showed a marked dimorphism in altered hepatic biochemistry upon admission, with a rise in those with normal liver enzymes upon admission (p=0.016, Kruskall-Wallis) and a drop in those with elevated liver enzymes upon admission (p=0.05); the latter was noted in subjects that had consumed alcohol close to the time of admission. Overall, however, IGF-I and IGFBP-3 were within normal limits for most subjects both upon admission and after alcohol detoxification; no significant differences were detected among the examined parameters in men vs. women, and there were no significant correlations of IGF-I, IGFBP-3 or the IGF-I/IGFBP-3 molar ratio with BMI or age.
    Conclusions:    Regardless of hepatic enzymes’ elevation, alcohol detoxification had overall slight effects on IGF-I and IGFBP-3.
